I'm trying to take a picture, save it on the internal storage and then show it in a imageview (cause i can't access internal storage and look for the image).
Taking the picture seems to work but loading the image to the imageview with the uri isn't working
(the uri returned by the intent is: "file:/data/user/0/com.packagename/filesfoldername/filename"). imageview stays empty.
private static String date = new SimpleDateFormat("ddMMyyy").format(new Date());
private File sessionDirectory=null;
private ImageView imgView;
private Uri HelpUri;
#override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode)
{
case REQUEST_IMAGE_CAPTURE:
super.onActivityResult(requestCode, resultCode, data);
if(resultCode==RESULT_OK) {
Toast.makeText(this, "Image Saved!", Toast.LENGTH_SHORT).show();
Toast.makeText(this, "Uri= " + HelpUri, Toast.LENGTH_LONG).show();
}
else
Toast.makeText(this, "Error Taking Photo!", Toast.LENGTH_SHORT).show();
break;
}
}
//Method creates an Intent to the camera - Capture an Image and save it//

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

} catch (IOException ex) {

}
if (ImageFile != null) {

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, ImageURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
else
Toast.makeText(this, "Problem Accessing Internal Storage", Toast.LENGTH_SHORT).show();
}
}
//Methods returns a File for the image file created on the internal storage//
private File createImageFile(String Pose) throws IOException {
if(sessionDirectory==null)
createSessionFolder();
if(sessionDirectory!=null) { //Succeed creating/finding the session directory

}
else
return null;
}

private void createSessionFolder() {
sessionDirectory = new File(getFilesDir()+"Session_"+date);
if (!sessionDirectory.exists())
if(!sessionDirectory.mkdirs()) //Tried to create the directory buy failed
sessionDirectory = null;
}
I would be greatfull if anyone can help.

Add provider path to res/xml folder. And declare it on AndroidManifest.xml. More information on here File Provider
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.package"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
Also do not forget to get permission from user.
public void verifyStoragePermissions(Activity activity) {
// Check if we have write permission
int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(
activity,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE
);
}
}

as described in the title I would like to save the image from camera in a specific folder and then view it in the gallery of my device. So far I can access the camera, take the photo and show it in an ImageView in the same layout. How could I do? I read on the net to use the provider but using it, the images taken with the camera are not displayed in the gallery of my device. Thanks in advance to those who will answer.
This is my code:
public class CamActivity extends AppCompatActivity {
private ImageView imageView;
private Button photoButton;
private Button saveToGallery;
private String currentPhotoPath;
private File photoFile = null;
static final int REQUEST_IMAGE_CAPTURE = 1;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_camera);

photoButton = findViewById(R.id.btnCaptureImage);
saveToGallery = findViewById(R.id.gallery_save);
photoButton.setOnClickListener(new View.OnClickListener() {

if(checkPermissions()) {
dispatchTakePictureIntent();
galleryAddPic();
}
}
});
saveToGallery.setOnClickListener(new View.OnClickListener() {
#Override

}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bitmap myBitmap = BitmapFactory.decodeFile(photoFile.getAbsolutePath());
imageView.setImageBitmap(myBitmap);
} else {
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
}

return false;
}
}
}
I have made a button which on clicks opens a camera and captures the image. But then it doesnot show on the imageview i made and doesnot even save in the gallery. I think i have written the right code but the flow seems to written in wrong way.
public class MainActivity extends AppCompatActivity{
static final int REQUEST_IMAGE_CAPTURE=1;
ImageView img;
String mCurrentPhotoPath;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn=(Button)findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
dispatchTakePictureIntent();
}
});
}
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_IMAGE_CAPTURE && requestCode==RESULT_OK )
{
Bundle extras=data.getExtras();
Bitmap imageBitMap=(Bitmap) extras.get("data");
img=(ImageView)findViewById(R.id.img);
img.setImageBitmap(imageBitMap);
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
}
In some context, we need to update media cursours forcefully to visible in mobile gallery. Therefore try below code segment to update your media forcefully.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(new File(...path of your image file))));
As I can see in your code, createImageFile() is not called any where. I think that inside your dispatchTakePictureIntent you should insert some additional code and make it this way:
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"YOUR_PACKAGE_NAME.provider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
And you should create, inside your xml folder under resources folder, a file named 'file_paths.xml' where you can write the code below if not yet done:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Android/data/YOUR_PACKAGE_NAME/files/Pictures" />
</paths>
Remember also to declare the provider in the Manifest file like this:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths" />
</provider>
Remember to replace YOUR_PACKAGE_NAME by your real package name. Then inside your onActivityResult method, get the bitmap this way:
File file = new File(mCurrentPhotoPath);
Bitmap bitmap = MediaStore.Images.Media
.getBitmap(getContentResolver(), Uri.fromFile(file));
img=(ImageView)findViewById(R.id.img);
img.setImageBitmap(bitmap);
Try step by step, refine if possible and give feedback. Ask for clarifications in comments but try first please.
I try to take and save photo in my app.
I wrote in manifest the fileprovider and path for him:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="mypacage.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/path" />
</provider>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="my_images" path="images"/>
</paths>
In my activity I call Fragment Dialog (cameraOrChoosePhoto Dialog) which have a button, next make intent for opening camera and other actions for create file for photo::
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.dialog_camera:
Uri uri = generateUriPhoto();
if(uri!=null) {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
cameraIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION |
Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
getActivity().startActivityForResult(cameraIntent, SubItemDetail.CAMERA_RESULT);
} else dismiss();
break;
case R.id.dialog_choose_photo:
break;
}
}
private Uri generateUriPhoto() {
file = createNameFile();
uri = null;
if (file != null) {
String aut = getActivity().getPackageName()+".fileprovider";
uri = getUriForFile(getActivity(), aut, file);
getActivity().grantUriPermission(getActivity().getPackageName(), uri,
Intent.FLAG_GRANT_READ_URI_PERMISSION |
Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
}
return uri;
}
public File getFile() {
return file;
}
public Uri getUri() { // onActivityResult
return uri;
}
private File createNameFile() {
directory = new File(getActivity().getFilesDir(), "images");
if (!directory.exists()) {
directory.mkdirs();
}
String name = "photo_" + System.currentTimeMillis();
File file = null;
try {
file = File.createTempFile(
name, /* prefix */
".jpg", /* suffix */
directory /* directory */
);
} catch (IOException e) {
e.printStackTrace();
dismiss();
}
return file;
}
Next on my activity:
.........
private Uri uri
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
CameraOrChoosePhotoDialog cameraOrChoosePhotoDialog = (CameraOrChoosePhotoDialog) getFragmentManager().findFragmentByTag("camera");
uri = cameraOrChoosePhotoDialog.getUri();// get uri from dialogfargment
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_RESULT) {
image.setImageURI(uri);
addPicToGallery(); // try to put photo in gallery
cameraOrChoosePhotoDialog.dismiss(); // close dialog
}
}
}
private void addPicToGallery() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,uri));
mediaScanIntent.setData(uri));
sendBroadcast(mediaScanIntent);
}
but the photo does not appear in the gallery
Try to convert the captured file into the image format such as .jpeg, .png etc. and then store it into the device local storage or SD card.
Replace your
private void addPicToGallery() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,uri));
mediaScanIntent.setData(uri));
sendBroadcast(mediaScanIntent);
}
with
private void addPicToGallery() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,uri));
mediaScanIntent.setData(Uri.fromFile(file)));
sendBroadcast(mediaScanIntent);
}
somehow initial uri from FileProvider is different from uri you get from actual file :)
I am trying to open camera in Marshmallow and nougat using FileProvider but not getting the bitmap to show captured image in imageview in onActivityResult method.Even i tried to get bitmap from image path. Here is my code

if (file.exists()){
if (file.delete()){
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(),"Deleted",Toast.LENGTH_SHORT).show();
}
});
}
}
}
catch (Exception e){
e.printStackTrace();
}
}
}
<?xml version="1.0" encoding="utf-8"?>

I don't know if your code doesn't contain everything. But here are some points to note:
You should save photos in the device public directory
Generally, any photos that the user captures with the device camera should be saved on the device in the public external storage so they are accessible by all apps.
(Taken from the docs)
If you do so - you need to declare the WRITE_EXTERNAL_STORAGE in your AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
With Android Marshmallow you have then request the permission for that. Here is a simplified version of that:
.
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 99);
...
....
#Override
public void onRequestPermissionsResult(final int requestCode, #NonNull final String[] permissions, #NonNull final int[] grantResults) {
// Execute your code to create the file and start the camera intent here
}
(Read more here)
You have also to use the getExternalStoragePublicDirectory from Environment as storageDir
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
Your file_path.xml should now point to Pictures/:
<external-path name="my_pictures" path="Pictures/"/>
In your onActivityResult you can simply use the photoUri field which you received from FileProvider#getUriForFile to set to the image:
imageView.setImageURI(photoUri);
For me the changes helps to make a working example:
I think you have to use this library for camera and gallery : https://github.com/jrvansuita/PickImage you don't needs to convert image in to bitmap.and this library is working fine in Marshmallow and nougat.
I have went through several documentation and stacks, however I'm not quite sure how do I implement this...
And help or sample codes would really help me understand more.
Here are the sets of codes that runs the camera and it's working perfectly fine, my next question is, how do I let it automatically saved into phone gallery?
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
tvCameraTiles = (TextView) findViewById(R.id.tvCameraTiles);
tvCameraTiles.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dispatchTakePictureIntent();
}
});
}
private void dispatchTakePictureIntent()
{
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null)
{
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK)
{
//Get Camera Image File Data
// Bundle extras = data.getExtras();
// Bitmap imageBitmap = (Bitmap) extras.get("data");
// mImageView.setImageBitmap(imageBitmap);
}
}
have you read this https://developer.android.com/training/camera/photobasics.html ?
Especially the part:
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
You don't seem to save the photo in the external storage, so it should work.
EDIT: I tried to make a really basic application following the documentation with the method galleryAddPic.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button photoButton = (Button) findViewById(R.id.photobutton);
photoButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dispatchTakePictureIntent();
}
});
}
static final int REQUEST_IMAGE_CAPTURE = 1;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
//Bundle extras = data.getExtras();
//Bitmap imageBitmap = (Bitmap) extras.get("data");
//mImageView.setImageBitmap(imageBitmap);
galleryAddPic();
}
}
String mCurrentPhotoPath;
private File createImageFile() throws IOException {
File storageDir = Environment.getExternalStorageDirectory();
File image = File.createTempFile(
"example", /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
ex.printStackTrace();
}
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
This is working for me! I take a picture using the camera app, and then it's showed in the gallery app.
I modified the code regarding the FileProvider part, now it passes the Uri with the help of the method Uri.fromFile(photoFile). I save the photo in a different position too, check the code in the method createImageFile for this one.
In the Android Studio emulator is working fine, let me know about you.
I tried out Rex B code snippet, but ended up getting a error on Android Studio.
android.os.FileUriExposedException: file:///storage/emulated/0/example6941495009290613124.jpg exposed beyond app through ClipData.Item.getUri()
If anyone got this error, I found a simple fix
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
I added these two lines to the onClick method
Button photoButton = (Button) findViewById(R.id.photobutton);
photoButton.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
dispatchTakePictureIntent();
}
});
}
I know this is old post, but I'm sure someone will come by this one day.
First the file will be created and the ByteStream will be written on the file and saved. you don't do anything for this file to be present in the gallery. This will automatically refreshed by gallery.
I have experimented for past 1 week with most of the stackoverflow threads but couldn't find a comprehensive solution, but all the threads helped me. Here is the working code which I have tested in Android 11,12 and 13(Google Pixex 6a)
AndroidManifest.xml will have the following
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
This what I have mentioned in provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<cache-path
name="cache"
path="." />
<external-cache-path
name="external_cache"
path="." />
<files-path
name="files"
path="." />
</paths>
call the below method on onclick event
dispatchTakePictureIntent();
In onActivityResult
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case STApplication.SHOW_TAKEPICTURE:
//Uri selectedImage=null;
if (resultCode == Activity.RESULT_OK) {
try{
//Bundle extras = data.getExtras();
Bitmap imageBitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), OldURI);
//galleryAddPic();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
try {
saveImageInAndroidApi29AndAbove(imageBitmap);
} catch (Exception e) {
//show error to user that operatoin failed
}
} else {
saveImageInAndroidApi28AndBelow(imageBitmap);
}
btnPicture.setText(getString(R.string.picture_taken));
} catch (Exception e) {
e.printStackTrace();
}
break;
}
}
}
Then finally include all the below methods and variables inside your activity class
String currentPhotoPath;
Uri ImageURI;
public static final int SHOW_TAKEPICTURE = 99;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

ImageURI=photoURI;
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, SHOW_TAKEPICTURE);
}
}
}
private File createImageFile() throws IOException {

// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = image.getAbsolutePath();
return image;
}
private boolean saveImageInAndroidApi28AndBelow(Bitmap bitmap) {
